Download Driver For Intel PRO/Wireless 2100 0.55

At Source Forge, a number of people are working with Intel on Linux drivers for the Intel Pro/Wireless 2100, a network card found in many Centrino laptops. The drivers only work on Linux with kernel version 2.6 or higher, and require Wireless Tools for Linux. To work with this version of the drivers, the firmware of the Intel Pro/Wireless 2100 must be updated to version 1.3. This firmware can be this one page are found. The changelog accompanying this release shows the following changes:

Changes in 0.55

• Fixed rmmod oops in ieee80211 (thanks to Yi Zhu and Stephen Hemminger)
• Merged into WPA code (thanks to Lubomir Gelo)
• Fixed stricter type check warnings (thanks to Pedro Ramalhais)
• Fixed ‘make uninstall’ to correctly remove the modules vs. the entire directory.
• Renamed ipw2100_main.c to ipw2100.c
• Fixed IPW2100_DEBUG_FW to IPW_DEBUG_FW
• Changed CONFIG_IPW2100_(WPA|WEP) to CONFIG_IEEE80211_(WPA|WEP)
• Makefile fixes to enable WEP during the build
• Masked out DEBUG_RX code paths by CONFIG_IPW_DEBUG (thanks to Dominik Bathon)
• Fixed suspend/resume (thanks to Yi Zhu)
• misc. code cleanups (extra casts removed, unused function warning) (thanks to Scott Feldman)
• Added filtering of corrupted 802.11 frames in rfmon mode (thanks to Jacek Wysoczynski)

Known issues in 0.55

• If C3 is enabled, you may occasionally see “Corruption detected at 0x….:” messages in your kernel log, followed by a firmware reset. A temporary work around is to disable the C3 low power state (either via the patch on the website to processor.c or by unloading the ACPI processor module).

Changes in 0.54

• Test fix for spurious IRQs during firmware initialization.
• Fixed payload_size bug in fragmentation code (thanks to Yi Zhu)
• Removed “IRQ ignored” message.
• Changed IPW2100_DEBUG and IPW2100_DL to IPW_DEBUG and IPW_DL
• Updated dvals script to report out debug levels
• Switched legacy fw loader on 2.6 to use vfs (thanks to Yi Zhu)
• Merged all .c into single file (same with .h) Removed ipwversion.h
• ipw2100_private_args and ipw2100_private_handler arrays are defined only once and CONFIG_IPW2100_PROMISC #ifdefs are moved inside array definitions (thanks to Lubomir Gelo)
• Removed get|set_preamble and get|set_longpreamble schizophrenia and fixes ipw2100_wx_set_preamble. Also removes unused long_preamble variable (thanks to Lubomir Gelo)
• Resynced ieee80211 with ipw2200 (moved scan and probe logic from ipw module into ieee80211 module)
